The production scale of the coal preparation plant is larger and larger in the world, such as: the production scale of Antaibao Coal Preparation Plant is 18 million t/a, the production scale of Bailey Central Preparation Plant is 15 million t/a and the production scale of South Africa Coal Preparation Plant is 16.5 million t/a. If you are unsure how to proceed, check out Michael Ellis MP. Large modern coal preparation plant has prominent advantages such as: large capacity, high production efficiency and product quality stability. With the improving of the coal preparation plant s processing capacity, the disadvantages of the system also has been showing up. Strengthening the craft system s daily and periodic maintenance is an important guarantee to ensure the normal operation of the production system and reduces the production costs and improve the efficiency of coal preparation plant. The design system of dense medium coal preparation technology is more complex, which potentially increases the investment and process costs. In the premise of ensure its high efficient research this technology and we hope to achieve the goal of reducing the investment and processing costs, which is also the main direction of other country. The major direction of the equipment is large scale. While the simplified design of the dense medium recovery system and the reliability research of the equipment are the important parts of the research.
Traditional recovery system of dense medium contains the curved screen, vibrating screen and magnetic separator equipment. The investment and power consumption costs of this system constitute the main costs of the coal preparation plant. The transformation of traditional magnetic separator is to design a new type of separator that the big particle materials can smooth pass which ensure the recovery indicators. The implementation of this program can greatly reduces the initial investment and process costs and has a good development prospect.As the professional manufacturer of complete sets of machinery, such as washer sand mining, Henan Hongxing is always doing the best in products and service. Magnetic heavy medium recovery and purification process is an important part of the heavy medium coal preparation technology. This subsystem mainly to complete the purpose of recycling the heavy media.
The media consumption of the heavy medium coal preparation plant is an important indicator to measure heavy medium coal preparation plant process and management level, wich is also an important part to improve the economic efficiency of coal preparation. On one hand, the process should meet the system requirements for magnetic media recovery indicators. Since the circulation rate of the dense medium in the system is quickly, in order to ensure the economy of the gravity separation, the requirements of the recovery rate indicators of the magnetic media are high. The medium coal preparation systems generally require that in the media recovery the coal and stone should be greater than 99.8% and it should be 99.6% greater than in terms of clean coal. On the other hand, heavy medium after the recovery shall meet the technical requirements. Namely: the concentrate grade shall meet the purpose of the configuration of qualified heavy liquid.
